Answer:

By substracting 0.16 from 0.35, we get 0.19. This is also true when we subtract 0.35 from 0.54. Thus, 0.19 is what we are adding to each previous term to get the next one. When we add 0.19 to 0.54, we get 0.73, and when we add 0.19 to 0.73, we get 0.92. Therefore, the next two terms in the pattern are 0.73 and 0.92.

Step-by-step explanation:

Answer:

0.73 and 0.92

Step-by-step explanation:

The difference of the first 3 is 0.19 per step, so continuing that is 0.73 and then 0.92

Answer:

r = 6

Step-by-step explanation:

The formula for the volume of a cylinder is  V = πr^2h,

If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards it can be written as 144π = πr^2 * 4

You can then solve for r by dividing both sides of the equation by 4π:

r^2 = 36

r = 6

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

they are all about archaeology

Step-by-step explanation:

archaeology is th name of the study, artifacts are what archaeologist study, and carbon dating is the way that archaeologist date the artifacts.

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

Steps:

6 1/4 - 4 3/15 can also be written as 25/4 - 23/5

The LCD of 4 and 5 is 20.

That gives us 125/20 - 92/20.

Now, just subtract the numerators (leave the denominators the same).

That brings us to 33/20, which can be simplified to 1 13/20

Final Answer:

\(1\frac{13}{20}\)

--------------------------------------------------------------------------------------------------------------

*Please mark brainliest if that helped!*

Answer:

1 \(\frac{13}{20}\)

Step-by-step explanation:

1. Convert both \(\frac{1}{4}\) and \(\frac{3}{5}\) into a common denominator. 4 multiplied by 5 is 20. 20 works for both 4 and five. So convert the denominator into 20. Multiply \(\frac{1}{4}\) by \(\frac{5}{5}\) and multiply \(\frac{3}{5}\) by \(\frac{4}{4}\)

2. You should've gotten, \(\frac{5}{20}\) and \(\frac{12}{20}\)

3. 6 - 4 = 2, so 2 \(\frac{5}{20}\) - \(\frac{12}{20}\)

4. You have to convert 1 into \(\frac{20}{20}\) and add that to \(\frac{5}{20}\). You should've got \(\frac{25}{20}\)

5. Subtract.

The Answer is 1 \(\frac{13}{20}\)

I believe I am correct.

Answer: D

Step-by-step explanation:

(A. 1.5 > 2 1/2

(B. 1/2 > 0.5

(C. -2.5 > -1.5

(D. -3 1/2 > - 4.5

Step 1: Convert everything to decimals or fractions so its easier to see and make it less likely to get the question wrong

Method #1: Fractions

1.5= 1 1/2

0.5= 1/2

-2.5= - 2 1/2

-1.5= - 1 1/2

-4.5= -4 1/2

Now we have:

(A. 1 1/2 > 2 1/2 --> This is wrong because 1 1/2 is supposed to be less than 2 1/2.

(B. 1/2 > 1/2 This is also wrong. 1/2 is equal to 1/2; they are obviously the same.

(C. -2 1/2 > -1 1/2 This is wrong because, in negative numbers, its sort of backwards. For example, -2 is actually less than -1 because its farther away from 0. But if they were normal positive numbers, 2 would be bigger. But here, -2 1/2 is less than -1 1/2.

(D. -3 1/2 > - 4 1/2 This is correct. -3 1/2 is closer to 0 than -4 1/2, so it has to be bigger.

Solving the problem this way gets me to: Answer= D

Method #2: Decimals (remember: same numbers, different way of writing them!!!)

(A. 1.5 > 2.5 False. 1.5 is less than 2.5

(B. 0.5 > 0.5 False. 0.5 is equal to 0.5

(C. -2.5 > -1.5 False. -2.5 is farther away from 0 so its actually smaller.

(D. -3.5 > - 4.5 True. -3.5 is closer to 0.

Doing it this way also leads me to Answer= D.

Hope this helps :)) Also can i please have brainiest? I worked pretty hard on this :D

Answer:

D. 4

Step-by-step explanation:

A straight line equals 180 degrees if there's already 140 degrees then you need 40 more to make the line true so 10 times 4 is 40 to make 140 + 40 = 180 true

Option D 78.5

Step-by-step explanation:

Circumference= 2*Pi*r

                        = 2 * 3.14 * 12.5

                        = 78.5

The circumference of the circular car tire is 78.5 inches.

Circumference of a circle is defined as the total length of the boundary of the circle.

The concept is same as the perimeter for straight sided figures.

Given that,

Radius of a circular car tire = 12.5 inches

We have to find the circumference.

The given car tire is circular in shape.

The formula to find the circumference of a circular shape is,

Circumference = 2πr, where r is the radius of the circle.

Substituting the given value of r,

Circumference = 2π × 12.5

                         = 25π

Given to use 3.14 for π.

Circumference = 25 × 3.14 = 78.5 inches.

Hence the required circumference of the circular car tire is 78.5 inches.

Answer:

\(x=-6\dfrac{7}{8}\)

Step-by-step explanation:

\(Solve\:9\:\dfrac{1}{4}\:+\:x\:=\:2\:\dfrac{3}{8}\)

Step 1:
Convert all mixed fractions to improper fractions.
This will make it easier to add and subtract

Mixed fraction \(a\dfrac{b}{c}\) can be converted to an improper fraction using

\(a\dfrac{b}{c}=\dfrac{a\cdot \:c+b}{c}\)

\(9\dfrac{1}{4}=\dfrac{9\cdot 4+1}{4} = \dfrac{37}{4}\)

\(2\dfrac{3}{8}=\dfrac{2\cdot 8+3}{8} =\dfrac{19}{8}\)

Step 2:
Replace every mixed fraction in the original equation with its equivalent improper fraction:
\(\dfrac{37}{4}+x=\dfrac{19}{8}\)

Step 3
Solve for x
